His vocals are definitely impressive; can't wait for the release of Catharsis, the falsettos are unreal
Dan is amazing.

God damn I love Dan.
Why, oh why, did he leave TesseracT?
Why, oh why, did he leave TesseracT 
One was perfect.
Holy shit this is pretty fucking good!
such an underrated vocalist
Wouldn't say he underrated; most people seem to love him.
These videos make me wonder why he buries his voice under so many effect when he sings really well life.
Did he do the vocals on the album? Because I just listened to a few of the tracks a couple days ago when I got the album and remembered thinking the vocals sounded exactly like TesseracT
Yeah he did all the vocals on the 'Illusion' disc. Fantastic singer.
And he never fails to deliver:
Absolutely, and he's said he will re-record Catharsis because he wasn't too happy with it.
